Cards (24)

  • What was the aim of Casey et al (2011) study?
    To assess delay of gratification's impact on adults
  • What does the study examine regarding adults who were high or low delayers as children?
    It examines their impulse and self-control abilities
  • What research method was used in the study?
    Quasi-experiment
  • What was the independent variable in the study?
    Whether the participant was a high or low delayer
  • What was the dependent variable in Experiment 1?
    Participants' performance on a go/no-go task
  • What additional data was collected in Experiment 2?
    Brain scan results from fMRI
  • How many children participated in the original delay of gratification task?
    562 children
  • How many participants were left by the end of the study?
    117 participants
  • How many participants took part in Experiment 1?
    59 participants
  • How many males and females participated in Experiment 1?
    23 males and 36 females
  • How many participants from Experiment 1 consented to the fMRI scan in Experiment 2?
    27 participants
  • What was the procedure for the go/no-go task in Experiment 1?
    Participants responded to facial expressions
  • What was the duration of each face stimulus in the task?
    500 ms
  • How many trials were presented in the go/no-go task?
    150 trials
  • What were the accuracy rates for high and low delayers in the 'hot' task?
    Low delayers had variable accuracy
  • What does the conclusion about hot and cool cues suggest?
    Hot cues affect temptation resistance
  • What was the hypothesis regarding brain activity in low delayers?
    Less activity in the right prefrontal cortex
  • What imaging technique was used in Experiment 2?
    fMRI (functional magnetic resonance imaging)
  • What was the mean duration of the inter-trial interval in Experiment 2?
    Mean 5.2 seconds
  • What were the overall accuracy rates for the 'hot' go/no-go tasks?
    Mean 98.2% correct hits
  • How did the right inferior frontal gyrus activity differ between high and low delayers?
    Low delayers had less activity during 'no-go'
  • What does the ventral striatum's activity indicate about low delayers?
    Higher activity in response to rewards
  • What does the study suggest about individuals who struggled with delay of gratification as children?
    They have ongoing difficulties resisting temptation
  • How does temptation resistance vary according to context?
    More tempting choices predict behavior regulation
